Description

L-α-Phosphatidic Acid, Dipalmitoyl (Free Acid) is a high-purity, synthetic phospholipid that serves as a fundamental building block in lipid biochemistry and membrane research. This compound is critical for studying cell signaling pathways, membrane dynamics, and lipid-protein interactions due to its role as a metabolic intermediate and signaling molecule. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise lipid components for drug delivery systems, diagnostic assays, and biomimetic membrane models.

Application

• Liposome & Drug Delivery System Formulation: A key excipient for creating stable, targeted liposomal carriers for pharmaceuticals and nutraceuticals.
• Biochemical & Cell Biology Research: Used as a substrate or standard in studies of phospholipase activity, lipid metabolism, and intracellular signaling cascades.
• Biomimetic Membrane Models: Serves as a critical component in constructing artificial membranes (e.g., supported lipid bilayers) for biophysical studies and biosensor development.
• Cosmetic & Dermal Formulations: Incorporated into high-end skincare products for its emulsifying properties and potential skin barrier repair functions.
• Diagnostic Reagent Production: Utilized in the manufacture of reagents for clinical diagnostics, particularly in assays measuring phospholipid-dependent enzymes.
• Food Science & Nutrition: Investigated for its functional properties as an emulsifier and its role in nutritional science research.

Quality Control

Every batch of our L-α-Phosphatidic Acid, Dipalmitoyl is produced under stringent quality management systems. We employ advanced analytical techniques including HPLC, NMR, and MS to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and specific tests is provided with each shipment, supporting compliance with research and cGMP-grade requirements for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation and hydrolysis. The material is hygroscopic (moisture-sensitive) and should be handled in a dry environment. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
